Portulaca plant named ‘SAKPOR006’

ABSTRACT

A  Portulaca  plant particularly distinguished by having a white flower color, flower blooming period from spring to fall and a semi-mounding, upright, and vigorous plant growth habit, is disclosed.

Genus and species: Portulaca oleracea.

Variety denomination: ‘SAKPOR006’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Portulacaplant, botanically known as Portulaca oleracea, and referred to by thevariety name ‘SAKPOR006’. ‘SAKPOR006’ originated from a hybridization inKakegawa, Japan in 2006 between the female Portulaca line ‘Mo04-19A-V2’,an unpatented proprietary Portulaca breeding line having a white flowercolor and bushy growth habit, and the male Portulaca line‘BB03-36A-2-V4’, an unpatented proprietary Portulaca breeding line witha rose flower color and bushy growth habit.

In August 2006, the female parent line ‘Mo04-19A-V2’ and male parentline ‘BB03-36A-2-V4’ were crossed and F₁ seeds were obtained. In May2007, the F₁ seed was sown in the greenhouse, cultivated and plant lineswere produced with rose, pink, and white flowers having a bushy planthabit. The plants were evaluated and plant line ‘K2008-187’ was selectedfor its white flower color, flower blooming period from spring to fall,and vigorous plant growth habit.

In May 2008, ‘K2008-187’ was vegetatively propagated, cultivated, andevaluated. In August 2008, ‘K2008-187’ was confirmed to be fixed andstable. In May 2009, May 2010, and May 2011, ‘K2008-187’ wasvegetatively propagated to reconfirm its stability. ‘K2008-187’ wassubsequently named ‘SAKPOR006’ and its unique characteristics were foundto reproduce true to type in successive generations of asexualpropagation via vegetative cuttings.

SUMMARY

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in Salinas, Calif.

-   -   1. White flower color;    -   2. Flower blooming period from spring to fall; and    -   3. A semi-mounding, upright, and vigorous plant growth habit.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctivecharacteristics of ‘SAKPOR006’. The data which define thesecharacteristics were collected from asexual reproductions carried out inSalinas, Calif. Data was collected on twelve-month-old plants grownunder greenhouse conditions in Salinas, Calif. in the fall of 2012.Color references are to The R.H.S. Colour Chart of The RoyalHorticultural Society of London (R.H.S.), 4^(th) edition (2001).

The            vegetative cuttings were propagated in five to six weeks.            The base of the cuttings were dipped for 1 to 2 seconds in a            1:9 solution of Dip 'N Grow (1 solution: 9 water) root            inducing solution immediately prior to sticking into the            cell trays. Cuttings were stuck into plastic cell trays            having 98 cells, and containing a moistened peat moss-based            growing medium. The cuttings were misted with water from            overhead for 10 seconds every 30 minutes until sufficient            roots were formed. Rooted cuttings were transplanted and            grown in 20 cm diameter plastic pots in a glass greenhouse            located in Salinas, Calif. Pots contained a peat moss-based            growing medium. Soluble fertilizer containing 20% nitrogen,            10% phosphorus and 20% potassium was applied once a day or            every other day by overhead irrigation. Pots were            top-dressed with a dry, slow release fertilizer containing            20% nitrogen, 10% phosphorus and 18% potassium. The typical            average air temperature was 24° C.-   Plant description:    -   -   Habit and form.—Semi-mounding, upright, and vigorous.        -   Life cycle.—Annual.        -   Height (from soil line to top of foliage).—Approximately            10.0 cm.        -   Spread.—Approximately 50.0 cm.        -   Flowering requirements.—Blooms repeatedly from spring to            fall.-   Stems:    -   -   General description.—Round, slightly rough with lateral            ridges.        -   Stem length.—14.0 cm.        -   Diameter.—0.3 cm.        -   Internode length (average).—2.0 cm.        -   Color.—RHS 146C (Yellow-Green) with RHS 182B (Greyed-Red)            anthocyanin.        -   Pubescence.—Absent.        -   Anthocyanin color.—RHS 182B (Greyed-Red).        -   Branching.—Abundant.-   Leaves:    -   -   Arrangement.—Alternate.        -   Shape.—Oblanceolate with cuspidate tip in mature leaves and            acute tips in younger leaves near the apex of the stem.        -   Apex.—Acute.        -   Base.—Rounded.        -   Margin.—Entire.        -   Surface appearance (both surfaces).—Dull.        -   Surface texture (both surfaces).—Smooth, no pubescence.        -   Length.—1.9 cm.        -   Width.—0.9 cm.        -   Thickness.—0.1 cm.        -   Color.—Upper surface: Closest to RHS 146C (Yellow-Green).

COMPARISON WITH PARENTAL LINES AND KNOWN VARIETY

‘SAKPOR006’ is a new and unique variety of Portulaca owing to its whiteflower color, flower blooming period from spring to fall and asemi-mounding, upright, and vigorous plant growth habit. ‘SAKPOR006’ isdistinguished from its parents mainly by flower color and plant growthhabit as shown in Table 1 below:

‘SAKPOR006’ is a new and unique variety of Portulaca owing to its whiteflower color, flower blooming period from spring to fall and asemi-mounding, upright, and vigorous plant growth habit. ‘SAKPOR006’ ismost similar to the commercial Portulaca variety ‘DPAZ17’, alsocommercially known as PAZZAZ™ ‘Jumbo White’, (U.S. Plant Pat. No.23,245); however there are differences as described in Table 2 below.
